| <h2>Description:</h2> |
| <p> |
| <div> |
| The goal of this manual test is to verify that observers that have |
| registered "event" entry type can observe the long-latency input events, |
| and verify the same behavior within iframe and in cross-frame scenario. |
| </div> |
| </p> |
| <h2>Manual test steps:</h2> |
| <p> |
| <div> |
| Step 1: Click the "make busy" button to make main-thread busy for 2 seconds.</span> |
| </div> |
| <div> |
| Step 2: do several clicks on "click while busy" while busy to generate long-latency inputs. |
| </div> |
| <div> |
| Step 3: observe in the "timeline" section that the long-latency clicks are captured by the observer. |
| </div> |
| <div> |
| Step 4: do step 1 to step 3 for the iframe. Observe that the observers only observe input events within its frame. |
| </div> |
